[0002] The discharge tube is a high-voltage protection element used at the input end of the device. If the voltage at both ends is higher than its protection specification value, a short circuit will occur inside it and absorb the input overvoltage. The switch discharge tube is a type of discharge tube. Different from ordinary discharge tubes, the switch discharge tube has strict requirements on its service life and failure rate per million due to its use in the automotive industry.

[0003] The switch discharge tube usually includes a central cylindrical main body and leads arranged at both ends of the main body, wherein the leads at both ends of the main body are used to access the line, and the switch discharge tube needs to be fixed by welding to complete the assembly production of the leads and the switch discharge tube. In general, the leads are first cut to obtain the effect of uniform length specifications, and then the main body and the leads are respectively transported to the welding position through an independent conveying system, and the main body and the leads are clamped and placed by a robot, and then the welding of the main body and the leads is completed before unloading.

[0004] In the above welding assembly process, since the leads need to be cut, an additional step is added, but there is still the possibility of simplifying the steps. Utility Model Content

[0005] In order to simplify the welding assembly process of the switch discharge tube, the present application provides a switch discharge tube welding production equipment.

[0006] The present application provides a switch discharge tube welding production equipment adopts the following technical solution:

[0008] By adopting the above technical scheme, the clamping cylinder drives the clamping rod to switch between the two states of clamping the lead and not clamping the lead. When the lead is clamped between the welding head and the clamping rod, the conveying cylinder drives the conveying platform to move toward the clamping assembly, which can bring the lead and the welding head into the clamping assembly to complete the welding fixation between the lead and the main body. Then the clamping rod no longer clamps the lead, and the conveying platform resets with the welding seat. The cutting assembly completes the cutting of the lead, and the assembly of the main body and the lead is realized. At the same time, the lead does not need to be cut and loaded separately, and can be directly cut after the assembly of the lead and the main body is completed. It is more convenient and the process is more integrated.

[0009] Optionally, it also includes a lead adjustment assembly, which includes adjustment pulleys that are staggered and rotatably mounted.

[0010] By adopting the above technical solution, the position of the lead is restricted by the lead adjustment assembly, so that the lead maintains the conveying direction, reducing bending and wear, and the use of an adjustment pulley is conducive to the conveying of the lead.

[0011] Optionally, the lead wire adjustment assembly includes a vertical adjustment assembly and a horizontal adjustment assembly in sequence along the lead wire conveying direction, the adjustment pulleys of the vertical adjustment assembly are arranged alternately up and down, and the adjustment pulleys of the horizontal adjustment assembly are arranged alternately left and right.

[0014] By adopting the above technical solution, the pneumatic clamp is used to clamp the main body, and the opening and closing clamping at a certain angle is adopted, which is conducive to the separation process after the vacuum adsorption rod rotates the main body.

[0015] Optionally, the transfer assembly also includes a vertical cylinder that drives the vacuum adsorption rod to move up and down, the lower end of the vacuum adsorption rod is provided with an arc groove that adapts to the outer wall of the main body, the groove wall of the arc groove is provided with a vacuum adsorption hole, the claw of the pneumatic clamp is provided with a placement hole for placing the main body, and the upper part of the claw is provided with an entry and exit slot connected to the placement hole.

[0016] By adopting the above technical solution, the setting of the arc groove of the vacuum adsorption rod makes it convenient to adsorb and pick up the main body, and the opening of the placement hole on the claw further facilitates the detachment of the vacuum adsorption rod after transferring the main body. The clamping process of the clamping component is not easy to interfere with the movement process of the vacuum adsorption rod.

[0017] Optionally, the vacuum adsorption rod grabs the second to last body on the vibration plate direct vibration feeder.

[0018] By adopting the above technical solution, when taking the second to last body, the last body can still rotate, reducing the friction between the body and the vibration plate direct vibration feeder when moving up. At the same time, the space between the two bodies is also larger, which is smoother than taking the last body.

[0019] Optionally, the vibrating plate direct vibration feeder is provided with a displacement piece at the conveying end, and the displacement piece is consistent with the main structure.

[0020] By adopting the above technical solution, the main body is driven by the replacement part, and the replacement part can be made of a material that is less prone to wear, has a longer service life, and is in a more stable state.

[0021] Optionally, the displacement member is rotatably mounted.

[0022] By adopting the above technical solution, the replacement part is rotatably installed, so that the replacement part can keep rotating and is not easy to fall off by itself.

[0023] To summarize, the clamping cylinder drives the clamping rod to switch between the two states of clamping the lead and not clamping the lead. When the lead is clamped between the welding head and the clamping rod, the conveying cylinder drives the conveying platform to move toward the clamping assembly, which can bring the lead and the welding head into the clamping assembly to complete the welding fixation between the lead and the main body. Then the clamping rod no longer clamps the lead, and the conveying platform resets the welding seat. The cutting assembly completes the cutting of the lead, and the assembly of the main body and the lead is realized. At the same time, the lead does not need to be cut and loaded separately. It can be directly cut after the assembly of the lead and the main body is completed. It is more convenient and the process has a higher degree of integration. BRIEF DESCRIPTION OF THE DRAWINGS
